A common method is to "research backwards" in building a questionnaire by first determining the information sought (i.e., Brand A is more/less preferred by x% of the sample vs. Brand B, and y% vs. Brand C), then being certain to ask all the needed questions to obtain the metrics for the report. Unneeded questions should be avoided, as they are ...
